Banggood Neje 7 watt 450nm laser engraver

Saw this show up in the emailbox for $150:

Assuming an appropriate enclosure, what thoughts do you have about this? It’s obviously somewhat minimalist and I wouldn’t run it without enclosing it.


Output Optical Power 2.5W

They are selling it based on the power consumed by the head, not by the optical power. That’s not awesome.

They overdrive the laser and cut the duty cycle to get the 7W output. They are a piece of crap that will die very quickly.
